ELECTRIC BUTTER GHURN Filed Dec. 9, 1951 2 Sheets-Sheet 2 Patented Mar.7, 1933 UNITED STATES GLADYS n. 'r. WILLIAMS, or cLnvnLAnn, "OHIOELECTRIC BUTTER CHURN Application filed December 9, 1931". Serial No.579,941.

The invention relates to a churn and more especially to an electricbutter churn.

The primary object of the invention 18 the provision of a. churn of thischaracter wherein the electric power unit is concealed or housed and thesame connected with the churn dasher so as to assure smooth and easyoperation thereof for churning purposes. Another object of the inventionis the provision of a churn of this character wherein the constructionthereof is an improvement over the subject matter of Letters Patent#1,106,006 dated August 4, 1914, the mechanism being of novel form andassembly. 7

A further object of the invention is the provision of a churn of thischaracter which is extremely simple in construction, thoroughly reliableand efficient inits operation, strong,

durable, and inexpensive to manufacture.

lVit-h these and other objects in view, the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawings, which disclose the preferred embodiment of theinvention, and pointed out in the claim hereunto appended.

In the accompanying drawings Figure 1 is a side elevation ofa churn con-30 structed in accordance with the invention.

Figure 2 is a front view thereof.

Figure 8 is a top plan view.

Figure 4 is a sectional view on the line 44 of Figure 1 looking in thedirection of the arrows.

Figure 5 is av fragmentary sectional view through one of the bearings ofthe churn structure.

Figure 6 is a perspective view with the parts of the bearing separated.

Similar reference characters'indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, the churn-comprises in its make-upa base 10 surmounted by front and rear posts 11 and 12 respectively,there being a pair of front posts and a single'rear post, these beingspaced apart in their vertical position and the base 10 has suitablymounted thereon an electric points.

motor 13 operated from electric house current or other current supply.Fitted about the motor and the lower portions of the posts is a casingor housing 14 provided at its front and opposite sideswith swingingdoors 15 so that access may be had to the housing at these The doors 15are supported upon hinges 16 and carry knobs 17 for-the manual openingand closing thereof."

The top 18 of the casing 14 constitutes a platform While superposed withrespect to V the latter is an upper platform 19, the latter formed withthe posts 11 and 12 and is disposed horizontally and likewise theplatform 18.

The churn proper comprises a receptacle 20 removably seated against abracket 21on the platform 18 and secured thereto by an arm 22 pivoted atone end to a'post 11. The pivoted arm 22 partially surrounds thereceptacle 20v and is held in place by a removable pin 23 mountedlinsaid arm and passing through a lug 24 on another post 11. The churndasher includes ahead 25 adapted to reciprocate in the receptacle 20 anda stem 26 secured to said head. The stem 26 is slidably fitted in acover 27 forthe receptacle 20.

Mounted in a suitable bearing 28 on the platform 19 spaced forwardly ofthe rear post 12 and also mounted in the latter is a horizontal drivenshaft 29, the mounting of which with the bearing 26, and post 12 eachincludes a stationary cone 30and a movable cone 31, the latter beingfast to theshaft 29 while. working between these cones are anti-frictionbearing balls 32.

On the rear end of the shaft 29 is a belt pulley 33 and likewise on thedrive shaft 34 of the motor13 is a pulley 35 and about these pulleys istrained an endless belt 86 so that 11. This crosshead through the mediumof rigid'arms41 carries a sleeve 42 centrally located with respect tosaid head and projected outwardly therefrom, the sleeve being fittedwith a coupling rod 43. The coupling rod l3 and dasher stem 26 aredetachably connected together by means of a pair of inwardly projectingyieldable latch dogs: 44 attached to the coupling rod 43 and adapted tointerlock with the upper end of the said dasher stem 26 so that when theshaft 29 rotates reciprocatory movement will be imparted to the said 7stem 26 for the working of the churn as should be obvious. V

In the practical use of the churn power is transmitted from the motor 13to the shaft 29 through the medium of the belt 36 and the crosshead 40reciprocates in response to rotary movement of the crank 37. The churndasher is rigidly secured tothe crosshead 40 so as to reciprocate inunison therewith.

The churn proper, that is, the receptacle 20 I can be readily removedfrom the platform 18 by releasing the arm22 and swinging the sameoutwardly, while the dasher stem 26 can be readilydetached from thecoupling rod 43 by disengaging the yieldable latch dog 44 from the upperend of said stem 26.

By the anti-friction mounting of the shaft 29- the same has free motion,with minimum friction.

\Vhat is claimed is g A churn of the character described comprising astationary bracket, a clamping arm pivotally supported andcooperatingwith the bracket for clamping a receptacle therebetweenuprights at opposite sides of the bracket and having grooves in theirupper portions, a crosshead between the uprights and slidably fitted inthe grooves therein and having a slot a projection on the crosshead andextended outwardly therefrom; a dasher reciprocatingly mounted in thereceptacle and having a stem, a coupling on the projection fordetachable connection with the stem, and a power shaft mounted midwaybetween the uprights and having a crank engaged in the slot in thecrosshead.

In testimony whereof I aflix my signature.
